In 2023, the highest rates of chlamydia in the U.S. were reported for the Black population, with men having a rate of 974.7 per 100,000 population and women a rate of 1,342.2 per 100,000 population. This statistic shows the rates of reported cases of chlamydia in the United States in 2023, by race/ethnicity and gender.

Rates of syphilis in the United States are higher among men than women. This is true for every race and ethnicity, although the difference varies greatly. For example, among the Black population, there were around 62.3 cases of syphilis among men per 100,000 population in 2023 and only 18.8 cases per 100,000 population among women. On the other hand, rates of syphilis among American Indians/Alaska Natives were similarly high for both men and women with rates of 63.6 and 52.9 per 100,000 population, respectively. What is syphilis? Syphilis is a common and treatable sexually transmitted disease (STD). Anyone who is sexually active can contract syphilis, however men who have sex with only men accounted for slightly more cases than other groups in 2022. There are four stages of syphilis, and each stage has different signs and symptoms. The stages are primary, secondary, latent, and tertiary. Syphilis can be cured with antibiotics. How many people get syphilis each year? In 2022, there were around 207,255 cases of syphilis in the United States. This was the highest number of cases recorded since the 1950s. In comparison, in the year 2000, there were only around 31,618 cases. Like chlamydia and gonorrhea, rates of syphilis in the United States have increased over the past couple decades reaching 62 per 100,000 population in 2022. However, this rate is still far below the rate of 146 cases per 100,000 population recorded in 1950. Rates of syphilis in the U.S. are highest among people in their twenties and early thirties.

In 2023, the highest rates of gonorrhea in the U.S. were reported among the Black population, with men having a rate of 712.6 per 100,000 population and women a rate of 413.9 per 100,000 population. This statistic shows the rates of reported cases of gonorrhea in the United States in 2023, by race/ethnicity and gender.

In 2023, there were an estimated 1.03 million cases of chlamydia among women in the United States and around 610,445 cases among men. Furthermore, that year, there were around 378,428 cases of gonorrhea among men and 221,176 cases among women. Despite the dangers of sexually transmitted diseases (STDs) being more commonplace and testing and contraception, for the most part, widely accessible in the United States, rates of chlamydia, gonorrhea, and syphilis, have all risen in recent years. Chlamydia in the United States According to the CDC, chlamydia is the most commonly reported bacterial sexually transmitted infection (STI) in the United States. In 2023, there were around 492 cases of chlamydia per 100,000 population, a substantial increase from a rate of 289 per 100,000 population in the year 2002. Those aged 20 to 24 had the highest rates of chlamydia in the U.S. in 2023. Although chlamydia often has no symptoms, it can cause serious health problems if left untreated, one of the reasons those who are sexually active should be regularly tested for STDs. Once diagnosed, chlamydia can be easily cured with antibiotics. Gonorrhea Rates of gonorrhea in the United States decreased after reaching a peak in the 1980s but began to rise again over the past decade. In 2023, there were 179.5 cases of gonorrhea per 100,000 population in the United States, compared to 98 cases per 100,000 population in the year 2009. While rates of chlamydia in the U.S. tend to be higher among women than men, rates of gonorrhea are higher among men, with those aged 20 to 24 the most affected. Like chlamydia, gonorrhea can be cured with medicine but can cause serious and permanent health problems if left untreated.

In 2023, only six percent of high school students in the United States reported being tested for sexually transmitted diseases (STDs) in the past year. This graph shows the percentage of high school students in the United States who were tested for STDs in the past year as of 2023, by race/ethnicity.

IMPORTANCE: In the United States, the prevalence rates of Human Immunodeficiency Virus (HIV) and sexually transmitted infections (STIs) are higher among individuals in community supervision programs (CSPs) than in the general population. However, to date, no couple-based HIV or STI prevention interventions have been implemented for the large number of men in CSPs. OBJECTIVE: To determine the effectiveness of a 5-session couple-based prevention intervention, compared with a 1-session counseling, testing, and referral (CTR) program, in reducing HIV and STIs as well as condomless intercourse among men in CSPs and their female sexual partners. DESIGN, SETTING, AND PARTICIPANTS: A randomized controlled trial was conducted from July 11, 2013 (first recruitment), through May 17, 2016 (last randomization). Participants were drug-involved men mandated to a CSP and their female sexual partners (n = 230 couples or 460 individuals). Participants were recruited from various CSP sites in New York, New York, and randomized into either the PACT (Protect and Connect) intervention condition or the HIV CTR control condition (n = 115 couples or 230 individuals in each arm). Analysis of behavioral outcomes used an intent-to-treat approach. Statistical analyses were conducted from November 1, 2017, through June 1, 2018. MAIN OUTCOMES AND MEASURES: Self-reported data on sexual behaviors in the past 90 days were used to assess behavioral outcomes at all time points. Biomarkers were collected at baseline and 12 months, and behavioral outcomes were collected at baseline and 3, 6, and 12 months. RESULTS: A total of 230 couples (460 individuals) were included. The mean (SD) age of participants was 35.0 (12.8) years, and most participants (341[74.1%]) self-identified as black or African American race/ethnicity. Of the 18 new cases of STIs identified at the 12-month assessment, 10 came from the PACT arm and 8 from the HIV CTR control arm. Compared with the control participants, PACT participants had 33% fewer acts of condomless vaginal and/or anal intercourse with their main partner (incidence rate ratio [IRR], 0.67; 95% CI, 0.45-0.99; p = .04), 70% fewer acts with other partners (IRR, 0.30; 95% CI, 0.12-0.74, p = .009), and 40% fewer acts with all sexual partners (IRR, 0.60; 95% CI, 0.42-0.85; p = .005) over the entire follow-up period. In addition, PACT participants were less likely to report being under the influence of drugs or alcohol the last time they had vaginal and/or anal intercourse with their study partners (odds ratio, 0.55; 95% CI, 0.31-0.96; p = .04) and had 26% fewer sex partners in the past 90 days (IRR, 0.74; 95% CI, 0.61-0.88; p = .001). At 12 months, HIV and STI incidence did not differ significantly between the 2 arms. CONCLUSIONS AND RELEVANCE: The PACT intervention appeared to reduce risky sexual behaviors, such as condomless intercourse; this finding suggests that a couple-based HIV and STI prevention intervention program may curb the burgeoning HIV epidemic in CSPs.

The states with the highest rates of HIV diagnoses in 2022 included Georgia, Louisiana, and Florida. However, the states with the highest number of people with HIV were Texas, California, and Florida. In Texas, there were around 4,896 people diagnosed with HIV. HIV/AIDS diagnoses In 2022, there were an estimated 38,043 new HIV diagnoses in the United States, a slight increase compared to the year before. Men account for the majority of these new diagnoses. There are currently around 1.2 million people living with HIV in the United States. Deaths from HIV The death rate from HIV has decreased significantly over the past few decades. In 2023, there were only 1.3 deaths from HIV per 100,000 population, the lowest rate since the epidemic began. However, the death rate varies greatly depending on race or ethnicity, with the death rate from HIV for African Americans reaching 19.2 per 100,000 population in 2022, compared to just three deaths per 100,000 among the white population.
